Abstract:

Conical shaped vehicles with high ballistic coefficients are subjected during re-entry, to intense fluctuating air pressures which result in high internal sound and vibration levels. As a result of these high vibration levels internal components can be adversely affected. In order to insure reliability, vibration, test criteria are predicted based on limited experimental data at high Mach numbers and generally result in conservatism of the design. This program using prior experimental data and high Mach number data obtained in the present contract, reviews existing analytical expressions necessary to define aeroacoustic loads associated with high beta re-entry vehicles and recommends analytical expressions for transitional, fully developed turbulent, separated and base flow.
